Anti-blocking domestic sewage treatment device with even aeration

Abstract

The invention relates to an anti-blocking domestic sewage treatment device with even aeration. The anti-blocking domestic sewage treatment device with even aeration comprises an aeration pipe, wherein an aeration mechanism and an anti-blocking mechanism are arranged at one end of the aeration pipe, the aeration mechanism comprises a connection box, a supporting assembly, a rotating assembly and at least two aeration assemblies, the connection box is cylindrical, the connection box and the aeration pipe are coaxially arranged, the aeration assemblies comprise fixing pipes, aeration disks and installation holes, the anti-blocking mechanism comprises an assisting assembly and at least two anti-blocking assemblies, the assisting assembly is arranged in the aeration pipe, the anti-blocking assemblies comprise sealing disks, the sealing disks and the fixing pipes are coaxially arranged, the diameter of each sealing disk is larger than the outer diameter of each fixing pipe, and the anti-blocking assemblies correspond to the fixing pipes in a one-to-one mode. According to the anti-blocking domestic sewage treatment device with even aeration, an aeration function is achieved through the aeration mechanism, moreover, an anti-blocking function is achieved through the anti-blocking mechanism.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an anti-blocking domestic sewage treatment device with uniform aeration. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of being discharged into a certain water body or reused. Among them, the aerator is one of the common equipment in sewage treatment. The aerator directly injects air bubbles into the untreated In sewage, under the joint action of coagulant and flocculant, the suspended solids undergo physical flocculation and chemical flocculation, thus forming large suspended solids flocs, which float to the liquid surface under the action of the bubble group to form scum , using a slag scraper to separate from water. [0003] During the operation of the existing aerators, because most of the aerators are intermittent aeration, and the solid content in the wastewater is high, the aeration hole tubes are o...

AI Technical Summary

Problems solved by technology

[0003] During the operation of the existing aerators, because most of the aerators are intermittent aeration, and the solid content in the wastewater is high, the aeration hole tubes are often blocked, which reduces the practicability. Not only that, the existing aerators The aeration position of the air machine is fixed, and the aeration uniformity is low, which greatly reduces the aeration effect
